Luger information

[Johnny Peppers]

Drop down and look at the picture of the 1900 Swiss posted by Doug as that is a long frame. As far as I know, all the Model 1900's had the long frame, while the 1902's used the short frame. The Model 1906 will be found both ways, but the long frame is scarce in the 1906. Some of the low production pistols between the Model 1900 and 1906 still used the long frame configuration.

There is approximately 1/16" difference in the length of the two frames, and the barrels for the two pistols will not interchange. You will occasionally see a short frame barrel that has had the shoulder set back to fit in a long frame.
